Problem:
A refinery’s “bad actor” vertical pump repeatedly failed despite multiple OEM repairs. During inspection, PRS discovered that the pump’s line shaft bearings were not positively located by fit, leading to misalignment and premature failure.
Solution:
Working with the refinery’s reliability group, PRS redesigned the bearing carrier to ensure proper alignment. PRS manufactured and installed the new parts during a routine repair, significantly improving run time and reliability.
Outcome:
The improved vertical pump has operated flawlessly for over two years without issue.
